Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1-Bromo-4-(but-3-yn-1-yl)benzene (CAS 765906-85-2), a certified reference material (molecular formula C10H9Br, MW 209.08 g/mol) for analytical method development and quality control.
1-Bromo-4-(but-3-yn-1-yl)benzene (C10H9Br) contains bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 1-Bromo-4-(but-3-yn-1-yl)benzene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
